Abstract
A diaphragm for a moving evil loudspeaker is formed of a material which has a mechanical "0"value of from 7 to 12, a Youngs modulus of from 8.5 to 17.5 x 105 KN/M2 and a density of from 0.85 to 1.05 g/cc. The diaphragm forming material is preferably formed of polypropylene or a propylene-containing copolymer. The diaphragm may be of cone or dome type and included are moving coil loudspeaker constructions wherein other vibrating elements, particularly spiders and outer cone support rings, are formed of the same type of material as the diaphragm.
